STOP-COCK.

Specification of Letters Patent.

Application filed April 4, 1907. Serial No. 366,300.

Patented April 28, 1908,

To all whom it may concern:

Be it known that I, WILLIAM W. MILLER, a citizen of the United States, and a resident of Shillington, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Stop-Cocks, of which the following is a specification.

My invention relates to cocks or valves in which a turning plug is employed having a limited rotary movement in the casing limited by a lateral projection provided upon the plug to contact with a stop or ofiset upon the rim of the casing.

My object is to simplify and improve the plug construction, and my invention consists in providing the plug with a separately formed sheet metal handle having an integral.

wing portion adapted to form such lateral rojection u on the plug when applied to the atter, as ful y described in connection with the accompanying drawing and specifically pointed out in the claims.

Figure 1 is a side elevation ofa cock embodying my invention. Fig. 2 is a se arate view of my improved separately ormed handle for the turning plug; and Fig. 3 is a separate view, of the slotted plug.

0 represents any ordinary cook or valve casing having a plug 0 ening intersecting the passage-way g, theret ough, and P represents an ordinary turning plug with lateral opening I) adaptedto register with said passage-way a or to close the same as desired. A portion of the rim 0 of the casing, as shown, is cut down to form ofi'sets d, as usual, for limiting the rotation of the plug; and a separately formed sheet metal handle H is secured to the protruding head or handle end 8' of the plug, which general construction is well known.

My improvement consists in so forming the sheet metal handle H and applying it to the plug, as to thereby provide the latter with the lateral projection whereby, in cooperation with the ofisets (1, its rotation is limited as desired; the object being to avoid the necessity of forming such projection by additional operations as heretofore, and at the same time secure a more permanent and satisfactory stop device. To this end I form the handle H with a depending wing portion formed integral therewith as indicated by punching the same from sheet metal without involving any additional operation whatever; and I so form the slot 9 in the plug head e that when the handle H is properly seated therein, said Wing f will project laterally from the inserted plug below the top of the casing rim; the slot g being cut obliquely, as shown, so as to firmly support said de ending wing portion of the handle when tiie latter is riveted or otherwise secured to the plug. By thus forming the lateral plug pro ection as an integral part of the sheet metal handle, not only is a considerable economy and great simplicity of construction attained, but greater rigidity and longer Wear are secured, with flatwise contact of the handle projection against the rim offsets d.

, What I claim is 1. A turning-plug for stop cocks having a sheet metal handle rigidly secured to the protruding head thereof and formed with a wing portion projecting laterally from the body of the plug to serve as a stop to rotary motion thereof in the casing.

2. The combination with a stop cock casing having an offset rim, of a turning plug having a protruding head provided with a handle-slot extending into the tapered body of the plug, and a sheet metal handle rigidly secured in said slot and formed with a wing portion projecting laterally from the body of the plug to serve as a stop against said rim ofl set, substantially as set forth.

In testimony whereof, I afiix my signature, in the presence of two witnesses.

WILLIAM W. MILLER.
